I rolled back our changes, so unfortunately not. I am using the RadCombobox in this particular instance. This only happens on the site with PageBlaster installed. All other sites allow this module and its controls to work without incident on any tab. I have tried adding rules in the Snapsis.PageBlaster.config file to troubleshoot and get around this, but they proved to not work. Here is the error that I received (only on certain pages) on the site that PageBlaster is installed: If RadComboBox is not initially visible on your ASPX page, you may need to use streamers (the ExternallCallBackPage property)
Please, read our online documentation on this problem for details http://www.telerik.com/help/radcombobox/v2%5FNET2/combo_externalcallbackpage.html And here are the rules I tried to add to the config file: [path pattern="(radcontrols)" excludeFrom="All" /] [path pattern=".*(/tabid/280/|tabid=280).*" excludeFrom="All" /] |
